To all whom it mag concern 1 3e it known that I, JOHN'W. SMITR, 8 @ltlZBll of the United.- States, residing at an'apparatus of this character adapted to be automatically operated by the engineer compressor to provide for a continuous circulation of watern the acket ofthe engine or compressor cylinder.

With the above and other ob 'ects' in view,

a the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed. In the accompanying drawings is shown a side elevation of an enginehavingapplied thereto a water circulating apparatus con-v structed in accordance with the invention.

Referring'more part cularly to the drawings, 1 denotes the engine, which may be of any form of internal combustion engine, the.

same being here shown in upright form. Counectedto the jacket 2 of the engine cylinder adjacent to its lower end is a coldwater inlet or supply pipe 3, the oppositesecured a reducing coupling 8, Withwhich, is connected one end of a small lIljectlng pipe 9. The opposite end of the pipe 9 is connected 'to a union 1(), to which is also connected a short nipple 12. The outer end. of the nipple 12 is connected to a curved or arched pipe 13, the opposite or lower end of The object of the invention'is to provide Connected to branch of which is connected by a nipple 15 -to the combustion" chamber of the engine. The free or lower branch of the coupling 14 hasconnected thereto a discharge valve 16, while in the pipe 13 above the coupling 14 is arranged a cut offvalve 17. v i

In the operation of the apparatus the Valve 16 is closed and the valve 17 opened immediately after the starting of the engine, so that as a: result of the explosions in the cylinder the'air will be driven through the pipe 15 into pipe 13 and through the reduced nipples onconnecting pipes 12 and 9and into the 'end of the pipe Tforcing the Waterthrough the same into the tank and drawing the water up through the pipe 5 to produce a vacuum therein, which will cause the water from the jacket to circulatearound through the same from the supply pipe 3 which is connected to a T-coupling 14, one

and to pass out of the discharge pipes o and into the tank, whereby thewater is cooled and 'again enters the lower end of the-jacket through the inlet or supply pipe 3.v

While the air pipe 15 is herein shown and. described as being connected directly to the combustion cylinder of the engine, it has been found that 'sufiicient pressure of air to operate the device may be had by connecting said pipe 13 with the exhaust pipe of the engine, thereby utilizing only a portion of the force of air resulting from the explosions within the cylinder.

When the apparatus Is not in iise or the.

engine not running the discharge valve 16 .at the lower end of the pipe 18 will be opened and the valve 17 closed, thereby preventing any'water from being drawn into the cylinder upon the starting of the en gine, said valve 16 being closed and the valve 1? opened immediately after the starting of the engine.

For the purpose of illustration the apparatus is shown and described in connection with an upright explosive engine. It will be understood however that the device-is equally well adapted for use in connection.

with air compressors and other forms of engines or motors, having a Water acket,

to'promote'a circulation of water therethrough. The device when used on air compressors is operated by a portion of the com-.

pressed air taken from the. compressor cylnuler.

connection with the accompanying draw v 13.0 From the foregoing description, taken in principle or sacrificing ings, thetconstruction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resortedto without departing from the any, of the advantages of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new is zf 1. The combination with an internal com,- bustion engine having the water jacket provided with an inlet and an outlet pipe, of an arched air-conducting pipe connected'at one end to the piston chamber. of said engine, a cut-ofl valve in said air pipe, and an injector arranged between and connected With the other end of said air pipe and the outlet pipe of said jacket to assist in draw ing the Water from the jacket and forcing ,1 it out through the discharge pipe.

2. The combination with a combustion engine'having a water j acketprovi'ded with an inlet and an outlet pipe, of an-arched airconducting'pipe adapted to be connected at 'one end to the combustion chamber 0% the engine, a cut-off valve arranged in said air pipe, a discharge valve arranged in the end thereof below the connection between said pipe and said combustion chamber, and a reduced detachable connection between the inner end of said air pipe and the water discharge or outlet pipe of the water jacket to form an injector for the air from said air pipe to said discharge pipe.

3. The combination with aninternal combustion engine having a Water jacket provided with an inlet and an outlet pipe, of an arched air-conducting pipe adapted to be connected at one. end to the combustion chamber of the engine, a cut-ofi valve arranged in said air pipe, a discharge valve arranged in the end thereof below the connection between said pipe and said combustion chamber, a reduced connection between the opposite end of said air pipe and the Water discharge pipeof said jacket, said connection comprising a union, nipples to connect said union with the end of the air pipe and w th a T-coupling arranged in said water discharge outlet pipe, and a reducing coupling between the endof one of said nippies and said T-coupl-ing. I In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
